    arm, mve: Fix scan-assembler for test7 in dlstp-compile-asm-2.c
    
    After the changes to the vctp intrinsic codegen changed slightly, where we now
    unfortunately seem to be generating unneeded moves and extends of the mask.
    These are however not incorrect and we don't have a fix for the unneeded
    codegen right now, so changing the testcase to accept them so we can catch
    other changes if they occur.
    
    gcc/testsuite/ChangeLog:
    
            PR target/117814
            * gcc.target/arm/mve/dlstp-compile-asm-2.c (test7): Add an optional
            vmsr to the check-function-bodies.
    
    (cherry picked from commit cf75f86ed980308621ab0db0dc8adc9c72e39f5e)
